Toma whom it may concern Be it known that I, AUGUST HEINE, a citizen ofthe United States, residing at Silver I Creek, in the county ofChautauqua and State 5 of New York, have invented a new and use. fulImprovement in Dust-Collectors, of which the following is aspecification.

. This invention relates to that class of dust collectors inwhich'theair. is filtered or sop-- IO arated from the dust by blowingthe dustladen air into a series of filtering tubes.

My invention has the objects to increase the efie'ctiveness of themachine, to improve the means for securing the filtering tubes in 15place, to provide-simple means" for automati: cally cleaningjthe tubesand to impr'ovethe 3 machine in other -respects. v

In the accompanying drawings consistingof three sheets:--Eigure 1 isa-longitudinal proved dust collecton Fig. 2 is a horizontal sectionthereof, in line v2-2, Fig. 1. Fig. 3 is a fragmentary cross section inline 3-3, Fig. 1; Fig. 4. is afragmentary sectional elevaz 5 tion, on anenlarged scale, of the upper portion of one of the filtering tubes andconnecting part-s shown in Fig. 1. Fig. 5 is a fragmentary sectionalelevation, on an enlarged scale, oi the lower portion of one of. thefiltero ing tubes and connecting parts. Fig. 6 is a longitudinalsectional elevation showing-another form of my improved dust-collector.Fig. 7 is a sectional elevation, on an enlarged scale, of the. upperportion of one of the fil- 5 teringtubes and connecting parts shown in.

Fig. 6.

Like letters of reference refer to .like wparts in the several figures.A A represent two receiving or settling 4o chambers arranged side byside. in the base of the machine and separated bya central partition a.The longitudinal sidos'of these chambersare inclined to form hoppers andtheir bottoms are provided with couveyer 5 troug'hsB 13',whicharearranged inline. The tops of the receiving chambers are closed bymanifold heads or decks C 0, each of which. is provided with an inletthroat d, and a group of circular tube openings (1. The inso let throatsof bothchambers are arranged on opposite sides of the central partitionandthe two groups of tube openings are uniformly disposed on oppositesides of the inlet throats. E represents an inlet chamber arrangedtransversely above the. receiving chamber 5 5 and provided with a closedtop, an open bottom and'atbothof its ends with inlet spouts e. The openbottom of the inlet chamber is connected with the throats of thereceiving chambers by a vertical air passage or expan- 6o sion'chamberFar-ranged between .the two groups of tubes and having its wallspreferably constructedof canvas or other filtering material.

4 G representsa cut off-valve arranged in the 5 lower portion of theexpansion chamber and adapted-.tocut oft communicationv betweentheexpansion-chamber andeither of .the 're-i ceiving chambers. This valve,is mounted with its lower end 'ona' transverse rod 9,, ar- 7'0rangedlengthwiseabbvethe upper endof the partition 0., and iscapable ofswinging with its free end against either side oithe'expansion chamberfor closing the throat of either of the receiving chambers. The rodgisjour- 7-5 nale'd with its endszin the sides of thereceiving chambersand is provided at one and out-- f side of said chambers with a'shiitinga m Tg' which is adj nstably secured with its free end to the segmentbya set screw.

H H represent two groups of filteringtubes of canvas or other suitablematerial, arranged vertically above the receiving chambersandcommunicatin'gat their lower ends with the tube openings of themanifold heads 0 C',re-- 85 spectively. Each of the filtering tubes isprovided at its lower end with a ring it which is somewhat larger indiameter-than the tube openings and is secured. to the tube'in anysuitable manner, preferably by lapping or 0 hemming the lower end of thetube around the ring, as shown. The lower fend.of' each tubular openinginrthe manifold head is provided with an annular enlargement forming ashoulder i. Each filteringtube extends up- 9 5 I wardly through a tubeopening and the ring at its lower end is seated against the shoulder ofthe opening. The rings of the tubes are preferably secured against theshoulders of the tube openings by staples it, which are roe driven intothe headsaud straddle the rings,

as shown in Fig. 5. This'means of securing fthe lowerends of thehue-ring; tubes is very? simple and convenient;
